Laminated glass is generally two sheets of glass with a tough plastic sheet sandwiched in between. It will generally crack and wobble a bit without forming a hole.
Toughened glass is the more usual windscreen one which shatters into bits max. about 10mm (and you find more of every time you clean your car afterwards!). I'm not sure which Triplex is - maybe a 3-layer laminated?
I have actually learnt this from kids throwing stones, albeit overnight at items of "plant" here in the UK. Excavators etc. generally have toughened when new, but in my experience laminated is the best replacement for this reason, so I guess it would be best also at withstanding African stones.
One other point (for flat windows) - Laminated can be cut "off the shelf", but toughened has to be cut and then heat-treated, so generally has to be ordered. Toughened's usually modestly cheaper though.
Funny, I read this thread before, but it didn't occur to me that I had had some stone-throwing experience!
